MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent `Nc. 366,558, dated'July 12, 1887.

Application filed May 16, 188.4.- Scrial No. 131.725. (No model.)

To all whom .it may concern:

Beit known that l, ANDREW BURGEss, a citizen of the United States, residing at Owego, in the county of' Tioga and State of New York, have invented certain new and useful Improvements in llIagazine-Guns, of which the following is aspeeifieation, reference being had therein to the accompanying drawings.

The object of my invention is to constr'ucta magazine-gun of great strength and easy lnani pulation; and said invention consists in locking and starting devices and modes of operating the slide, lock, and extracting devices, together with various combinations and arrangements'of' parts hereinafter more fully described.

Figure 1 is a longitudinal sectional side elevation showing the bolt locked by braces B the bolt also, by a direct-acting. sliding rod. Fig. 2 is a view similar to Fig. 1, but in which the bolt is locked byltwo braces and moved by a slide, which is provided with gearing to reverse its movement and increase its power. Figs. 3 and 4 show modifications in unlocked position of' the upper brace of' Figs. 1 and 2 and modes of operating it. Fig. 5 shows the face of the bolt with extractors. Fig. 6 is a sectional side View of a bolt. showing a modification of the. extraetors. Fig. 7 is a top view of bolt with locking-brace B' hung therein.

the starting-lever of Figs. 1 and 2. Fig. 9 is a longitudinal section, partly in elevation, showing the operative mechanism with breech open.

Similar letters of reference indicate corresponding parts.

A is the frame of the gun; B, the bolt; S, the operating-slide; R,- the operating-rod; B', the brace carried by the bolt; B2, the brace pivoted in the frame; p, the pin or connection of the two braces, and H is the grip to hold t-he cartridge-head againsttherextractor.

The operating-slide S beneath the gun moves the rod R,which engages the bolt or the brace B", by means of the rolls or projections 1 o", to move the bolt to unlock, open, close, and lock it. n Vhen the rod R moves back in Fig. 1, the roller r first engages the brace B2,- which is pivoted in the frame to move it back so far fromagainst its locking-shoulder in the bolt that the-roller r (after first moving back the firing-pin' by engaging its projection f) may move the bolt back by engaging the shoulder r of lhebolt, and in the last part ot' its backward movement the roll 1" strikes the hammer to cock it. A

The ordinary mainspring, s, has a projection, s',which extends forwardof the hammerpivot to there engage the pin s? andrebound the hammer,.so thatits face shall retire as on the line a: below the line of movement of the firing-pinfso that the bolt or 'firing-pin may not have to expend the power heretofore used when the bolt first starts back to compress the mainspring. I show another spring, y, attached to the carrier, which may serve alone as a mainspring or in conjunction with the other.

The carrier has a raised top or ear extending from its front backward, as in Fig. 1, c, which has a still higher portion, c'. When the bolt is closed and the rod R in its forward position, the projection or roll r of rod R presses the carrier 4down to its lowermost position to allow a cartridge to pass from the magazine partly onto the carrier, as shown in broken lines, Fig 1; but when the roll fr is drawn back of c the. carrier is raised alittle by spring 1, so that the top of' ear c rests against the roll r while the .bolt is yet locked, and the carrier is high enough to obstruct the magazine by its face, after having risen a little, as described, at the time the breech or rod It is back, so the cartridge can only enter upon the carrier when the breech is fully closed,and the next cartridge in the magazine cannot enter on the earrier'when the breech is partly open.

The fly f is arranged in the carrier at rear of its raised ear c, so`that when the roll r or faceof the bolt opens back to the rear of cthey engage the fly to hold the carrier down while the breech is opened to near its extent, when and the hammer may be easily cocked, as before described, and .when thebreech is being closed and is forcing down 'the carrier by the bolt or roll .by the impingemeiit of said bolt or-roll against the rear of ily f', and ear c of, carrier it tightens -the tension onl and gives more force to the mainspring` The spring y Ais stopped bya fixedpin, y', when the ham# mer falls, to permit said hammer to reboundA for the purpose before described.y

Ihang the extractor in one side of the face of' the bolt and arrange a lever or grip, H', in the bolt having a part, 71., which is projected forward of the bolt opposite the extractor bya fixed point in the frame, as seen in Figs'. 1, 2, and 6, when the breech is closed, so it shall grip the head of the cartridge opposite the ex;- tractor to prevent the said cartridgehead from rising; but when the breech is opened the lower part vof the lever H (reaching another point or stop, as l1?, fixed in the frame) is turned to retire the grip-point h back evenwith the face of the bolt, so the cartridgeis free to riseor be expelled upward or out of the frame by the extractor (which may serve then as an ejector) or the rising carrier.. JIn lthe modifi.4 cation, Fig. G, a similar lever operates the` sliding dovetail grip H. To increase the .power of the slide S vin starting'openand thel last part of the motion of closing the breech, I pivot a lever, 1l, to said slide S, Figs. 1 and 2, so that said lever shall have al ring or handle projecting below its pivot, and above said pivot a point of engagement orfulc'rnm, as t,

so that when the handle of said lever is pressed in the direction of movement of the slide (which may be in lhe'act of moving said slide) the. rear arm, t5, of the lever engages the fulcruin t to force the slide backward, and the forward arm, t, operates in a similanmauner to force the sli'de' forward.- l' -1' I 'arrange a spring-dog, t2, -in the slide Sto engage a notch, t3, in lever-T, when said lever turns-to open the breech, so'that the said leverv,may not returnwhen the'lreehis' being closed c until the 4dog Freaches a* stop', las't,to stop.l said dog and release thelevery so it may act onits fulcrum tforce'the"last part of the movement of the slide S in closing the breech.

In Fig. 2'1 show the slide S provided with a gearing or ratchet-bar to engage and Aturn agear-Wheel, IV, which hangs on av pivot -xed to the body of 'the arm; The gear-wheel has fixed to its side a smaller' gearfwheeh '111,'

which in turn engages a ratchet-barf,.;R, which is a continuation of operating-rod.. Rif

By this arrangement I reverse lthe movement of the slide S and greatly increase its power in 'opening and closin the breech. t 7 I show a locking-braee,'

, In Figs. 1, 2, an B, hung on a pivot, b, in-the bolt,with its rear end turned upward to lock forward of the shoulder Ain' the Atop ofthe frame. The for-l ward end of brace B is connected by :an oblique slot and pin to-the operating-rod R, so that'said connecting-pin, as p, when guided in a backward linefof movement (straightv or curved) Aoperates obliqucly in the slot of the forward arm to raise or'lower it, and thereby unlock orlock the rear arm. .of brace 'B for ward of the shoulder` A; In unlocking the brace B its rear endrengages and cams back' the iiringpin.

I forma proj forward as the brace is unlocked against a pin,

ection, Z2, on brace Bto turn 13,*which thus lserves ias a fulcrum, and the.

brace Bv as a lever togstart back the bolt. I

show an independent lever in Fig. 8, whichoperates in a similar manner; Y .A

Figs. 3 and`4 show' modications of brace'B and of the mode' of connecting it to `the rod'B or supplementary brace B". The brace B", Fig. 2, is hung in the frame to' lock the bolt obliquely, in a-well-'known `manner-,but lIA herel combine it withl the brace B' to insure very great locking'strength. `'Il-he rod R vibrates the 'brace B2 back and forward to unlock vand lock thebreeeh by, engaging isaid.' vbrace with the projections r r of said rod, and--v thepin p of brace BzA engages in the oblique slot of brace B to operate it, as before described, and the bolt is also moved' back after being unlocked by the engagement'ofpin 'p in the slot of brace B. .v

The brace B2 when turned back also engages the hammer by dog or link o, which is attached to the brace B2 nearer its pivot than the point of its engagement with the hammer isto't'he pivot of said liauime-rfso that the free end of brace-B2 has greater movement in cocking than the distance traveledby thel striking' part of the hammer, thusmaking thev operation of cocking the hammer more'. constant /I show the link oattaclied to the hammer' .-by'a slot and pin, tofallow the hammer` 4to ,move independent Vof the brace, but dohot.

confine myself to lthat''.con'striiction, as a dog The tooth p ofthebolt is shownas a rounded the boit, rig. i.

It is'not essential in this invention that lthe hammer be rebounded by any kind of spring,"

.may engage a simple notch, or various .other` connections serve to produce thev same-result.- c

as a'simple stopping ofthe force of its propel-f' L .ling device, so that'the hammer may be irce to turn back on-theline x' a: to below the pathv of the firing pin or bolt, and thereby avoid the vforce hitherto foundA necessary to start 1 back the hammer by the first part of the back: ward movement of the bolt when great powermechanism,

Patent, is-

s'eassa 3 may be needed to start the shell thereby, and the grip to hold the cartridge laterally against the extractor, may bc reciprocated either way by a spring or other known means.

I do not herein claim, broadly, the brace B', without its forward extension, operated by a reciprocating rod to lock the bolt against the top ofthe frame, as Imake such broad claim in `my application No. 132,094, filed May 19, 1884.

I do not herein claim the striking up ofthe pivoted ejector by the carrier, the same being part. of the subject-matter of my application No. 216,814, of October 2l, 1886.

In my application No.I 224,139, filed Jaunary 12, 188i", I show a mainspring connected to the eartridgecarrier. such combination, broadly, in the present application, and not in the application of January 12, 1387. l
